a full, clear, and exact description, such as' will enable others skilled in the art to which it appertains to make and use the same.

This invention broadly relates to window constructions, but more particularly it concerns improvements in windows which are ordinarily subjected to severe usage, such as in railway-cars, boats, or other units of transportation.

.This invention has in view, among other objects, a mechanism which will positively hold a sash in any raised position and which may be so released by a slight pressure of the fingers that the sash may be freely adjusted to any other position.

Another object of this invention is to formulate a means for facilitating the positioning of windmv-sashes in their frames in such a manner that they will be positively secured in place and remain undisturbed notwithstanding the vibrations of the car or other structure by which they are carried.

Another object of this invention is to devise an instrumentality whereby the elimination of all binding friction at the sides thereof will be completely effected during the raising or lowering of a sash.

Another objectY is to produce4 a sash-affixing means which is simple in structure and. composed of few parts, all of which are adapted for being .made at a modicum of cost and so formed individually as to be capable of being readily assembled into a neat and coinpact arrangement susceptible of effective use in accomplishing the purposes intended.

Other objects and advantages will be in part obvious and in part pointed out hereinafter.

With these and other ends in view this invention accordingly consists in the features of construction, combinations of parts, and arrangement of elements hereinafter more explicitly set forth as an exemplification of the underlying principles involved in the invention.

in order that this invention may be more fully understood and made clearly comprehensible to others skilled in its relating arts,

drawings illustrating one embodiment of the 5 5 same are appended as a part of this specilication, and while the underlying principles of the invention maybe otherwise applied by modifications falling within the scope of the claims the herein-stated form is preferably 6o employed in ordinary practice and is regarded as a substantial improvement over the many implied and obvious variations of the same,

In the drawings it will be observed that like numerals denote corresponding parts throughout all the figures, of which- Figure l is a sectional perspective to the rear of a window construction embodying7 the invention, parts being broken away to more clearly show certain details. elevation with parts removed, showing the adopted arrangement of the various features.

Fig. 6 .is a vertical sectional view of the releasing mechanism as taken along line' 6 t5 of Fig, 2.. ,Fig. 7 is a section taken along line 7 7 of Fig.' 2 to show certain details of the release lfor the4 positive lock.

In carrying out the invention, some suitable means operative to securely Vposition a sashv in its frame will be employed'. For this purpose the instrumentality disclosedv in a copending application, Serial No. QliSJOO, 9o

will be found to be most effective in,use; but it to be `understood that the application of the herein-described invention is not limited to any particular sash-securing mechanism,

as it may been'iployed in connection with 95 certain other forms. Since, however, it is preferable to use the same in the herein-disclosed arrangement, it will be convenient to describe it in such relation. rlo this end a casing l forms a part of the frame within roo cross-section, the front and rear sides thereof 105 being respectively indicated by Eventi-4. Such sides embrace or straddle the protruding rib V.1 of the frame, and the lateralrela- Fig. 2 is a front 7o tonshipis' such that side i will normally slide in contact with such rile?. `Means are also provided for normally pressing together rib 2 vand side dwith a euiicient-orce to aiford enough friction therebetween to prevent any sliding whatever whenever it is desirable to have the sash and `frame be so secured to- ,ge-ther. The means, which is in the nature of a clog, may also lconveniently afford frictionv between other moving1 surfaces. Ordinarily it will be best to loeate this means within the.

space between side 3 of the trame and rib 2, and it is thus shown hy the drawings. in this emhodiment such means consists of a shoe 5," whieh is slidahly carried hyy the sash and adapted to he brought with considerable iorceagainst r'hZ, so as to securely clamp the same between such shoe and the outer wall i or the sash. As will he coinprehended, this mechanism constitutes a clog or frictionaiording member which is so mounted that hy a vintnfeinent thereof or of certain features thereof it will he brought firmly into a sash-securing position. This action may he realized in various ways, hnt that shown is regarded as the'rnost improved type and consists in movahly ,mounting the clog on the sash and utilising cam-surfaces in such a manner that a movement of the clog in a ver tical direction or of any part thereof will set up suiioient friction to positively retain the sash in any desired place in the frame, A Thus,

' as shown, the shoe is provided with an in clinedj slot 6, within which slides a-'st'ud 7, which protrudes trom thesash. Qhviously 4a downward movement of the shoe or clog will clamp the sash in place, while, on the oontrary, an upward movement thereof will release the same. it is tobe noted in this connection that to all prat purposes such releasing action entirely eliminates all ofthev binding riction'hetween the sash and the frame and that the iforrner may he freely raised when'so released. A mechanism is rovided for normally keeping the clog in et tective state, usually 1ny-nieans of an elastic i yield-provided'by springs, such as 8 and 9.

- ticularly in a means for rendering the a The gist of thisinvention resides more arfldresaid or other saslnaiining mechanism operative or inoperative, as may he desired.l As vwill be clear, it is highly' desirable that the adopted means be both eil'ectiveand easy in actuation. This invention .contemplates a means whereby a movement of the lingers, such as a horizontal motion, will he transn formed into an actuating clog movement, which, as shown in the now-described illustrative embodiment, may be vertical. To this end an extension l() from the clog means is pivoted to a revoluble rod 11, the latter being cranked, as shown by 12, 'whereby' a rotarymovement of such rod may be transformed into the desired reciprocatory movement of the clog. Therevoluble rod 1i is so mounted senses in the lower part oi the sash as to be incapablo oi a longitudinal movement, being retained in place by means of suitable bearing' plates 13.

To render the rod or actuator-rod 11 adaptable to being conveniently actuated through manual manipulation, it is axis, being pivoted to the lower partjof the.

sash at a point 19 intermediate its length in order thatl a motion ofthe linger end 17 Will result in a contrary motion atthe hell-cranklever-engaging end 18. Adjacent this lingerlever 17 is a companion finger-'lever 2.0, the

latter serving, as here shown, to actuate a yositive lock in cooperation with the friction.

lock or elog above referred to. These fingerlevers normally -have their exposed ends spaced apart, being urged into such osition e en sol by means ofaretracti spring 9. positioned, as shown by Fig. 2, the sash is in an immovable relation with respect to the frame, hut when'the vends are brought-into proximity b `the lingers, as shown in Fi s. 1 and 5, the c o is no longer effective an the sash lmay be rreely raised orlowered within the frame. This motion may be readily fol-` lowed by means of the arrows shown in Fig. ,I

re-v ferredto resort to a sim le inter osed ink IOO 1, from which it Willbeseen that asa' consequenceof bringing to ether the ex ose'd ends -of the finger-levers t e clog 5 wil be vraised and retracted from the rib 5 The positivey lock' acting in conjunction with the friction-lock consists in this embodiment of a'pair of longitudinally-slidable .bars 21 and 25', having endsadapted to. engage with suitable studs, as that shown by 22. `Bar 21 has its inner endA inturned, yso as not --to interfere With the Vrevoluhle rod, and pivoted at 23 to the lower endof lever 24.A

The corresponding bar 25' extends from the opposite side of the sashinto a pivotal oonneetion 26 at the upperendof lever 24, the

. fixed pivot of which liesj'intermediate the connection with thelock-bars'. Finger-lever 20 is in engagement with the upper 'end of such lever at point 27. It will now be observed that a reciprocatio'n of lever 20 toward its companion lever 17 will .so swing the bars-Vas to withdraw them from under studs 22, andupon releaseof the lingers from such levers spring 9 will .at lonce draw lthem togetherat their inner ends and bring both the positive and the friction locks into operative position.' 'j

will thus be seen that a mechanism has provided which is well adapted to aciish the several objects of this invention. arranging the linger-levers in the shown biinrcated manner it becomes possible to simultanedusly operate both the friction and positive locking means by a simple clomovement of the "fingers, and because of the positive erlinking between the various i'eatures ol.l t ,invention such simultaneous action is insured. Furthermore, since the bearing are substantially all entirely pivotal in nature but little friction is afforded by the operation of the release. Substan tially the entire pressure ofthe fingers is accordingly transn'iitted directly to the clog and the operation ol'Y the latteris rendered the more etl'ective both with respect to the release and the forward throw thereof.

ns many changes could be made in the above construction and many apparently widely dill'erent embodiments of my invention could be made without departing from the scope thereof, l' intend that all matter contai ned in the above description or shown in the accompanying drawings shall be in= terpreted as illustrative and not in alimiting sense. l desire it also to be understood that the language used in the following claims is intended to cover all of the generic and speci'lic teatures ot the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to tall thereilietween.
